a graduate student of neuroscience from cambridge, massachusetts... an attorney from jersey city, new jersey... and our returning champion, a medical student from plano, texas... and now here is the host of "jeopardy!" -- alex trebek! [ applause ] thank you, johnny. thank adies and gentlemen. our young champion here, jason, wins in many different ways. he'll build up a great lead in jeopardy! and double jeopardy! and then miss the final jeopardy! clue, but it doesn't matter, he's got so much money at the end of the game. he's been very impressive. but jennifer and bryan are young, bright, and eager to replace him.
